So far there are no connections between the above persons. Source for Anna and Minna is the State Archive of Latvia. Waldemar migrated in 1947 to Australia, where he died in 1994. Inta appears as a bookwriter in 1999 and in the telephone directory of Riga.

I wrote to Inta and received an answer. Her ancestors came to Hirschenhof / Lativa around 1766 due to an call from Tsar Katharina II.

I found in the churchbook of Hirschenhof in the years 1785 three mentions on Roggenbuck. One as a witniss to birth (Anna Maria Roggenbuck), one Communion (without first name)and one burial(Anna Roggenbuck).
